Overview
This OEM control board kit (part number 1183618) is the integrated furnace control (IFC) brain of the ICP / Tempstar / Heil RGS102LTCB0AAA gas furnace. The board sequences the entire heat cycle — it manages the inducer, igniter, gas valve, and blower timing, monitors the limit and flame-sense circuits, and stores diagnostic fault codes on its LED. When the board fails from a power surge, a blown onboard fuse, cracked solder joints, or burned relays, the furnace can short-cycle, fail to ignite, leave the blower running constantly, or go completely dead. This factory kit restores correct ignition sequencing and safety monitoring.

Installation Guide

- Access — Remove the blower compartment service panel to expose the control board.
- Document — Photograph every wire harness and plug location before disconnecting — terminal labeling is critical.
- Remove — Unplug all harnesses, remove the mounting screws, and lift out the old board.
- Install — Mount the new board with the included hardware and reconnect each harness to its matching terminal per your photos.
- Test — Restore power, run a full heat cycle, and confirm proper inducer, igniter, gas, and blower sequencing with no fault codes on the LED.
